3 years ago


Answers : (1)

                                        integral lim x=0 to infinity x^2/x^2sin^2xe^2cos^2x
=integral lim x=0 to infinity 1/sin^2xe^2cos^2x
=1/e^2integral lim x=0 to infinity4/(2sinxcosx)^2
=4/e^2integral lim x=0 to infinity dx/sin^2(2x)
=4/e^2 integral lim x=0 to infinity cosec^2(2x) dx
=4/e^2 [(-cot2x)/2] x=0 to infinity
=2/e^2[-cot infinity+ cot0]

Integrate x sin(2x) dx
Integrate the original integrand by parts: ∫ xsin(2x) dx Let f'(x) = sin(2x) f(x) = -cos(2x) / 2 Let g(x) = x g'(x) = 1 ∫ f'(x)g(x) dx = f(x)g(x) - ∫ f(x)g'(x) dx ∫ xsin(2x) dx = -xcos(2x)...

We know that, tan(c-b) = (tan c – tan b)/(1+tan c * tan b), So, (1+tan c * tan b) = (tan c – tan b) / tan (c-b), Put c= x+a, b=x, (1+tanx * tan(x+a)) = (tan(x+a) – tan x) / tan(x+a-x)...
